# Minor NSR Applicability and Program Requirements

3

## What are the Minor NSR applicability and program requirements? • Sources below major NSR thresholds • Not many requirements prescribed in our rules

– Mainly for public participation at 40 CFR 51.161(a) - (d), 51.166(q), and 52.21(q) 

### • Great deal of variation among state Minor NSR programs • Proposal represents how EPA would implement program in Indian Country in the absence of an EPA approved plan 4

## Why do we need Federal NSR rules in Indian Country? • Provide a permitting mechanism • Fill existing NSR program gaps • Promote economic development

5

## How will tribes benefit for the proposed Federal NSR rules? • Protect Tribal sovereignty • Provide equal opportunity for economic development • Build Tribal capacity

6

# Specifics of the Proposed Tribal Minor NSR Rule

7

## What is a threshold and what are examples of the proposed Minor NSR thresholds? • Limits below which minor NSR does not apply • Lower in nonattainment areas For example:

– Ozone attainment areas – 10 tpy NO 2
– Ozone nonattainment areas – 5 tpy NO 2 

### • Not the most nor the least stringent limits

– 42% of VOC sources will be below thresholds

– 76% of SO 2 sources will be below thresholds 8

## What are the proposed Minor NSR rule requirements? • Case- by- case control technology review • Air Quality Impact Analysis (AQIA) in rare cases • Monitoring, recordkeeping, and reporting as needed to assure compliance • Public participation, administrative and judicial review 9

## What are the proposed types of Minor NSR permits? • Typical/common type of permit • Source-wide permit • General permit • Synthetic minor source permits
10

# Permit Types Examples

11

## Example 1: What may be the appropriate controls for this asphalt batch plant? • Source information:

– Process capacity of 300 tons of asphalt/hour

– Dryer burner capacity of 60 MMBTU/hour • Area information:

– Area in attainment for all pollutants Emit PM Emit PM Emit PM Emit PM, CO, NOx, SO 2 , and VOC Emit PM ROADWAYS http://www.carolinaasphalt.org/docs/presskit/CAPA_Asphalt_Process.PDF • Permit information:
– Source owner applying for a typical/common permit

12

## Which controls did the reviewing authority determine were needed? • PM/PM - 10:

– Dryer will need a cyclone and a baghouse.

– Screens/bins/mixer will need a capture system (hood).

– Roadways will need dust suppressants

– Conveyor transfer points will need shrouding (screen or cover at transfer points)

– Aggregate piles will not need to be controlled 

### • NO 2 

### , VOC, and CO:

– Dryer and mixer have to combust natural gas or Liquid Petroleum Gas (LPG) with good combustion practices 

### • SO 2 

### :

– No controls needed, pollutant being emitted in amounts lower than proposed minor NSR threshold 13

## What are the steps for this particular permitting process? • Reviewing authority:

– Determines that AQIA is not needed

– Develops draft permit • subject to 30-day public comment period



### – Issues the final permit 

## • Permit highlights:

– The baghouse will have: • Exhaust limits for PM/PM - 10, NOx, VOC, CO • To comply with an initial compliance test, re -tests every 3 years • To be subject to inspection and maintenance program 14

## Example 2: What would a minor source PAL permit look like for a lumber mill? • Source Information:

– See diagram • Area information:

– All pollutants emitted in minor amounts • Permit Information:

– Owner requests minor source PALs for PM - 10 and VOC

– PALs established based on allowable emissions in tpy

http://plantsci.sdstate.edu/woodardh/Soils_and_Ag/Black_Hills/ Waste chipsfired boiler Emit PM - 10 Emits PM - 10 and VOCs Emits VOCs Emits PM - 10 Emits PM - 10 Emits PM - 10

## • Reviewing authority:

– Performs case - by- case control technology review • Determines no controls required for PM and VOCs • Determines that AQIA is not needed



### – Develops draft permit • Any modifications allowed if emissions stay within PAL limits • Monitoring will be done to assure compliance with the PALs based on:

– Actual mass emissions for each 12 - month period, rolled monthly

– Site-specific emission factors developed through testing • Subject to 30-day public comment period



### – If all conditions are met, permit is issued 

## What are the next steps in this particular permitting process?

16

### • Source Information:

– Comprised of compressors and related auxiliary equipment that emit CO, NO 2 , PM - 10, SO 2 , VOC 

### • Permit Information:

– EPA develops general permit after public participation process

– To qualify for coverage facility must not exceed the following limits:

– PM - 10 – 10 tpy

– SO 2 – 25 tpy

– VOC – 25 tpy

– CO – 95 tpy

– NO 2 – 95 tpy http://www.eia.doe.gov/kids/energyfacts/sources/non - renewable/naturalgas.html 

## Example 3: What would a general permit look like for a natural gas gathering facility?

17

## • To comply with PM - 10,VOC, SO2 

## , CO, and NO2 

## emissions limits: • Burn natural gas in compressors 

## • To comply with SO2 

## emissions limits: • Burn natural gas with a sulfur content less than 154 ppm and conduct periodic testing 

## What are the necessary conditions for this type of general permit?

18

## • Reviewing authority determines that AQIA is not needed • Owner of planned new facility applies for coverage under the general permit

– Includes an initial performance test for CO and NO 2 

## • Reviewing authority sends a letter of approval (or disapproval)

– If approved, owner posts notice of approval at the site and starts construction of the facility as permitted 

## What are the next steps in this particular permitting process?

19• Source Information:

– PTE for VOC is 400 tpy at 24 hrs/day, 7 days/wk (8,760 hrs/yr)

– Actual operations are typically 8 hrs/day, 5 days/wk (2,080 hrs/yr) • Area information:

– Area in attainment for VOC and ozone • Permit Information:

– Owner requests a synthetic minor permit 

### Plywood http://www.essexcoatings.com/http://www.forestlearn.org/mills/plywood/plytour/green_sorting.htm 

## Example 4: What would a synthetic minor permit look like for a plywood furniture factory?

20

### • Source must submit a screening modeling analysis to show that NAAQS are not threatened • Reviewing authority develops draft permit

– Permit limits operating hours to 5,000 hrs/yr for VOC:

– Reduces VOC PTE to 230 tpy

– Allows for increased utilization at facility 

### • Permit subject to 30-day public comment period prior to issuance • Facility must track and record actual hours of operation to show that the 5,000 hrs/yr limit is being met 

## What are the next steps in this particular permitting process?

# Specifics of the Proposed Tribal Nonattainment Major NSR Rule

22

## Which sources would be subject to the proposed Major Nonattainment (NA) NSR rule? • New major sources • Major modifications

23

## What would the proposed NA Major NSR rule require? • Lowest Achievable Emission Rate (LAER) • Offsets at prescribed ratios • Monitoring, recordkeeping, and reporting as needed • Public participation, administrative and judicial review • Same requirements as current NA Major NSR rules for areas lacking an implementation plan – 40 CFR part 51, Appendix S 24

## What are the proposed options for offset waivers? 1. Economic Development Zone (EDZ) option

– If sources located in a zone targeted for economic development. Criteria for this waiver:

• Demonstration that emissions will not interfere with attainment of the applicable NAAQS by the attainment date 

### 2. Appendix S, Paragraph VI option

– If sources will comply with implementation plan limits and not interfere with attainment date. Criteria for this waiver:

• Applicable until attainment date for NAAQS passes. 25

## Delegation, Permitting, Public Participation, and Administrative and Judicial Review Provisions for Both of the Proposed Rules
26

## What are the proposed delegation requirements? • The tribe:

– Must be recognized by the Secretary of Interior

– Laws must provide adequate authority

– Must demonstrate technical capacity and resources 

### • EPA retains all enforcement authority • Tribes may implement their own program through a Tribal Implementation Plan (TIP) 27

## What are the proposed requirements for obtaining a Minor or Major NSR source permit? • Source submits a complete application • The reviewing authority:

– Has 45 days to determine if permit application is complete

– Will perform control technology review on a case - by- case basis

– May require an Air Quality Analysis 

### • Then, the reviewing authority will:

– Develop the draft permit

– Provide public with a 30-day comment period

– Issue final permit if all applicable requirements have been met 28

## What are the proposed public participation requirements? • Public notice with 30-day public comment period • Public notice may be posted at locations such as trading posts, libraries, post offices, etc., as appropriate • Opportunity for a public hearing, if sufficient interest • Draft permit, application, and justification for permit issuance/denial available for inspection at:

– EPA Regional Office

– At least one location in the area, for example at the Tribal environmental office 29

## What are the options for permit appeals? • Any person may appeal the final permit if the:

– Person commented on the draft permit; or

– Grounds for appeal occurred after public comment period ended 

### • Two proposed options for permit appeals:

– Administrative – through Environmental Appeals Board (EAB)

– Judicial – through Federal Court of Appeals for the tribal area
30

## What are the requirements for administrative permit appeals? • Appeals must be filed within 30 days after a final permit decision has been issued • Upon filing of a petition for review, the permit will be stayed • Motion to reconsider the final EAB order must be filed within 10 days • If all remedies are exhausted, person may appeal to Federal Court 31

## What are the requirements for judicial permit appeals? • Permits:

– are effective upon issuance

– not stayed by filing for an appeal • To stay a permit, petition under the Administrative Procedures Act (APA) 5 U.S.C. 705 must be filed 

### • Source can have permit revoked after proceeding with construction while appeal was pending
